Vintage vinyl or new reissues?


Can someone comment on this subject. Preferably someone who has compared the old with new reissues. For example would a new sealed bob dylan highway 61 revisted, released by columbia always sound better than good reissues? How does one approach this question?
In the context that both the records are clean, mold, warp and scratch free and in like new condition. This thread is not about price but about which, if executed properly, will deliver the best SONIC results. Thanks.

I second the notion that the 45s add a whole other element into the equation. All the ones I own are astounding if not always mastered to me liking.
I've had the opposite impression regarding the recent sundazed reissues. My Blond on Blond is absolutely terrible. I dont know if I just got a bad copy or what.
One thing to bear in mind is that "good" and "bad" are not very descriptive. Different people like different things and different systems will show up different things. Not everyone likes "cleaner", or "warmer'" or "brighter" or whatever.
Ive got all the fantasy 45's released to date and many of the originals in excellent condition to compare them with playing back on a high quality system. In almost every case the 45's improve on the originals, more so on riversides and fantasy than say blue note and also with some classic record reissues at 33. even some of the ojc's hold thier own next to many originals. the point is that the really prime titles in mint condition on say bluenote are going to be impossible to find and prohibitively expensive and many of the reissues are as good or better.
